LOCK.

sPEoIFIoATIoN forming part of Letters Patent No. 631,431, dated August 22, 1899.

Application filed January 21,1899- Se'rial No. 702,909. (No model.)

To all whom it nutty concern.-

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, county of King, State of WVashington, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

My invention relates to improvements in looks; and my object is to provide an improved eseutcheon-plate therefor, especially for such a lock as is adapted to be inserted in the notch of a door and shown, for instance, in my Patents .Nos. 626,340 and 626,341, granted June 6, 1899.

In the accompanying drawing, showing the preferred embodiment of my invention, A represents the main portion of the escutcheonplate,and B a broadened projection at one side thereof, preferably opposite a spindle-hole H. This broadened projection is intended to cover up the slot in the stile of the door in the manner shown in my said patents. The plate is preferably cast of some metal, with a strengthening-rib O integral therewith and running around the rear face of the plate. D D are other strengthening-ribs, also cast integral with the plate, running across the rear face of the plate, preferably from one side rib to the other and branching to form ribs E and F. G G are other strengtheningribs, also cast integraland aidingin strengthening the plate and broadened projection B.

L L are flanges projecting from the rear face of the plate, preferably running from near said spindle-hole H out along the broadened projection. These flanges are preferably parallel and may form guides for holding in position a lock-frame such as shown through whicha fastening means, such as a wire, may be inserted to retain a lock-frame in position, one side of which frame may obviously lie behind such a wire.

K K are abutments at the side of the spindle-hole, against which the frame may rest. internally-threaded lug also projecting from the rear face of the plate and adapted to re ceive a screw projecting from the other escutoheon-plate, as shown in my said patents, and PP are screw-holes at the corners of the plate.

The ribs preferably have their faces in the same plane, so that when the escutcheonplat-e-is applied to the stile of a door these ribs will lie against the flat face thereof. The ribs are preferably cast integral with the plate and greatly strengthen it, while doing away with the necessity of a thicker plate, thus economizing metal. The'ribs D D and G G prevent the plate being bent overa longitudinal axis, and the ribs 0 O preventit from being bent overa horizontal axis. The ribs F also brace the plate and further strengthen it.

It will be obvious that many changes may be made in the construction herein disclosed Without departing from the spirit of my invention.

What I claim is 1. An escutcheon-plate embracing a main portion, a hole therein, a broadened projection from one side thereof substantially opposite said hole, and a flange projecting from the rear face of said plate and running from near said hole out along the rear face of said projection.

2. An escutcheon-plate embracing a main portion, a hole therein, a broadened projection from one side thereof substantially opposite said hole and an internally-threaded lug projecting from the rear face of said plate.

3. An escutcheon-plate having a pair of substantially parallel guides projecting from the rear face thereof, said guides having holes therein substantially opposite each other.

Signed at New Britain, Connecticut, this 19th day of January, 1899.

BYRON PHELPS.
